BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed August 9, 1910. Serial No. 576,401.

To all whom it may concern:

Be it known that I, STUART EDWARD BELL, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Bottle-Closure, of which thefollowing is a specification.

This invention relates to bottle closures and particularly to that classof bottle closures which are secured to the bottle in such a manner asto prevent fraudulent use of the bottle after the removal of thecontents, and one of the main objects of the present invention is toconstruct a closure of the class described, which is of simple andeconomical construction, and which may be readily applied to the bottlewithout the use of special machinery.

Other objects and advantages will hereinafter appear in the followingspecification.

Referring to the drawings which are for illustrative purposes only:Figure 1 is a vertical sectional View of a bottle, and closure embodyingone form of my invention. Fig. 2 is a vertical sectional view of theupper portion of the bottle shown in Fig. 1, with the closure removed.Fig. 3 is a horizontal sectional view on line m m Fig. 1. Fig. 1 is avertical sectional view of the closure removed from the bottle. Fig. 5is a perspective view of the metal cap forming a part of the closure.Fig. 6 is a perspective view of a preferred form of the metal cap. Fig.7 is an enlarged horizontal sectional view of a closure having the formof metal cap shown in Fig. 6.

1 designates a bottle having a neck 2 formed with a shoulder 3. Theportion of the neck above the shoulder 3 is tapered upwardly to themouth 4 of the bottle, as shown at 5, the neck including the taperedportion 5 being turned during the molding operation for the purpose ofproducing a true round outer surface on the neck of the bottle.

The closure consists of a cap 6, formed of thin metal, having a flat top7 and tapered sides 8 formed with a stepped rim 9 termi nating in anoutwardly extending flange 10. The stepped portion 9 and flange 10 areembedded in a ring 11 of glass, molded thereon and having the innersurface or face 12 of the ring molded in tapered form to fit the taperedportion 5 of the neck of the bottle. The inner face 12 of the glass ring11 forms a continuation of the tapered sides 8 of the cap 6 and togetherform a tapered surface which fits the tapered portion 5 of the neck ofthe bottle. The stepped portion 9 and flange 10 insure the cap beingsecurely anchored in the glass of the ring 11, and prevent relativemovement therebetween, at the same time forming a reinforcement of theglass ring.

In the preferred form of cap shown in Fig. 6 and Fig. 7, the steppedportion 9 of the cap is perforated as shown at 13, so that the glass ofthe ring 14 may flow through the perforations, thereby more intimatelylocking the cap 6 and the ring 14 together.

After the bottle has been filled the tapered portion 5 and the shoulder3 of the neck of the bottle are coated with liquid glass or othersuitable cement, and the closure placed over the mouth of the bottle,the under side of the glass ring 11 being seated on the shoulder 3, andthe cap 6 resting on the upper end of the neck of the bottle, thetapered walls 8 of the cap and the inner face 12 of the glass ringfitting snugly the ta-.

pered portion 5 of the bottle neck 2. The cement on setting firmly,seals the glass ring 11 of the closure to the neck of the bottle, andbecomes'permanently attached thereto. The liquidrglass or othercementing material is applied to the neck of the bottle as a very thinfilm or coating, and the glass ring 11 is seated thereon and is pressedinto close contact therewith. This prevents any great portion of cementused from being exposed to the action of any dissolving agent such ashot water which is ordinarily used for dissolving liquid glass, andowing to the thinness of the cementing agent and its inaccessibility toany sharp pointed instrument, it is impossible to dig or scrape suchcementing material from between the glass ring and the neck of thebottle.

To remove the contents of the bottle, the metal cap 6 is punctured orcut, the glass ring 7 and sides 8 of the metal cap remaining cemented tothe bottle in such a manner that to remove them would necessitatebreaking the neck of the bottle.

It is understood that I do not limit the scope of the invention to theparticular construction of the closure shown, but desire it understoodthat every form of closure be included having a metal cap secured in aglass ring, which is seated upon the bottle neck to form a closuretherefor.

lVhat I claim is:

1. A glass bottle and closure therefor, comprising a metal cap extendingover the mouth of the bottle and an insoluble glass ring molded on saidcap; said glass ring being arranged to encircle the neck of the bottleand contact therewith and to be in dependently cemented thereto.

2. A glass bottle and closure therefor, comprising a metal cap extendingover the mouth of the bottle and an insoluble glass ring molded thereon;said glass ring being adapted to encircle the neck of the bottle andcontact therewith and to be independently cemented thereon, said bottlehaving a tapered neck portion to receive said closure and contact withsaid glass ring, and a shoulder on the bottle adapted to have the glassring seated thereon.

3. A bottle closure comprising a bottle having a tapered neck, ashoulder on such neck, an insoluble glass ring adapted to encircle suchtapered neck and contact therewith and to be independently cementedthereto, said ring being arranged to seat upon the shoulder, and a metalcap having a flange cast in such glass ring.

4. A glass bottle and closure therefor. comprising a metal cap extendingover the mouth of the bottle, and having a stepped rim, a glass ringmolded on the stepped rim and independently cemented to the bottle, saidbottle having a tapered neck portion to receive said closure, and ashoulder on the bottle adapted to have the glass ring seated thereon.

5. A glass bottle and closure therefor comprising a metal cap extendingover the mouth of the bottle and having a perforated rim portion and aglass ring molded on the rim portion and. cemented to the bottle; saidbottle having a tapered neck portion to receive the closure, and ashoulder on the bottle adapted to have the glass ring seated thereon.

In testimony whereof, I have hereunto set my hand at Los AngelesCalifornia this 4th day of August, 1910.
